v0.14.0

Dragonfly v0.14.0

Some prominent features and fixes.

• Fixed a bug that caused linker incompatibility on some Linux distributions.
• Release of a Debian package (currently only for x86_64 architectures) - now it's much easier to install Dragonfly as a service on a linux machine.
• http_admin_console flag is renamed to primary_port_http_enabled. This controls whether --port accepts http requests as well. Also, we added new flags like admin_port and admin_bind to listen on an additional port. Please note that admin_port always exposes the HTTP interface #709
• Replication is almost ready - one can set up a master/slave setup with a usual "replicaof" command on a secondary replica (FAILOVER is not supported yet)

v0.13.1

Dragonfly v0.13.1

Minor bugfix

Don't miss the previous v0.13.0 Highlights:
The first release of the year! Yey!

This release contains a few exciting features.

• Active defrag: any long-running process with non-trivial allocation patterns suffers from excessive memory usage due to external fragmentation. This release uses an improved defragmentation algorithm after we released the initial version in the previous version.
• Experimental SSD-based data-tiering support. Dragonfly is the only in-memory store that provides data tiering that is faster than other memory-only stores. (Currently only for strings). Try it with flag --spill_file_prefix=<nvme_file_basepath>
• JSON - this release compliments the already existing JSON API with support for SCAN and TYPE working with JSON data types.
• Replication (still not for prod use) but can already be tried on simple single key commands like SET, SADD, ZADD, LPUSH etc.
• Writes and reads of large string values are optimized for x86 architectures with SIMD instructions.
• Numerous improvements to helm templates, plus docker health checks - thanks to @tamcore !

What's Changed

• Update README.md by @brunopicinin in #631
• fix(server): version check bugs by @romange in #632

v0.12.0

Dragonfly v0.12.0

This release is mainly about bug fixes and extending our codebase to support replication.

• Dragonfly can now connect as a replica behind Redis master (supports REPLICAOF command)
• Dragonfly can now connect to another Dragonfly instance to form DF->DF replication. This feature is not fully implemented yet but
  it performs the first part, namely "full sync stage". Now we are working on "stable state replication".
• Dragonfly now supports the active-defrag feature. See #448 for more details.

Huge thanks to all the contributors! ❤️

v0.9.0

Dragonfly 0.9.0

YOM KIPPUR edition

This is quite significant release with lots of interesting features:

• Epoll support - now we support all Linux kernels !!!
  Dragonfly automatically falls back to epoll API if iouring API is not available for some reason.
  This can also reduce friction when running Dragonfly on k8s (no need to use --privileged flag anymore).
  If you want to force epoll instead of iouring you can do it with --force_epoll flag.
• New Dragonfly specific command SADDEX key seconds member member ... allows adding to sets members with TTL!
• CPU usage is greatly reduced when Dragonfly is in idle mode (~10x reduction).
• Dragonfly can connect to Redis server in SLAVE mode (using replicaof command)
• MOVE, SORT and PERSIST commands are now supported.

Huge thanks to all the contributors! ❤️

v0.8.0

Dragonfly 0.8.0

A nice release, not very big but things are moving in the right direction.

1. Transactional support is extended to WATCH/UNWATCH by @dranikpg
2. A new SET data-structure was introduced by @braydnm . It can potentially provide for up to 50% memory savings when using small records in the set. See dense set doc for more details. You can start using the upgraded set with --use_set2 flag when running dragonfly.
3. JSON.DEL was added to JSON family by @iko1 .

Huge thanks to all the contributors! ❤️
